Mugwort

Artemisia vulgaris

Also calledBeifuß (German) · Artemisa (Spanish) · Armoise commune (French) · Nagadamani (Sanskrit, as applied in some Ayurvedic texts) · Běi ài 北艾 (Chinese) · Mucgwyrt (Old English)

A tall, silver-backed roadside perennial named for Artemis, goddess of women and childbirth. It is the first of the Anglo-Saxon Nine Herbs, and in late summer one of Europe's worst hay-fever plants.

Artemisia vulgaris, commonly known as mugwort, common mugwort, or wormwood, is a species of flowering plant in the daisy family Asteraceae. It is one of several species in the genus Artemisia commonly known as mugwort, although Artemisia vulgaris is the species most often called mugwort. Mugworts have been used medicinally and as culinary herbs. Wikipedia

§1

What it can do

  1. iSilvery, felted leaf undersides reflect heat and carry aromatic oil glands
  2. iiSpreads by rhizomes and can regrow from small root fragments, making it hard to eradicate
  3. iiiReleases huge amounts of wind-borne pollen; the allergen Art v 1 is a leading cause of late-summer hay fever
  4. ivIts aromatic compounds repel insects; sprigs were laid in shoes and linen

Eatenyoung leaves and shoots (sparingly) · flower buds (flavouring)

Used as a bitter flavouring for fatty meats and goose and, historically, in gruit ale before hops. It contains thujone, so avoid large amounts and avoid it entirely in pregnancy. Can cross-react in people with celery or spice allergies.

European folk medicineBitter tea for poor appetite, indigestion and irregular or painful menstruation; laid in shoes against travel-weariness
Traditional Chinese MedicineMugwort leaf (ai ye, mainly the related A. argyi) is dried into moxa and burned over acupuncture points (moxibustion)
Ayurveda / South Asian folkLeaves used for worms, fevers and menstrual complaints

Weight of evidence

Traditional. Long historical use; little or no modern clinical evidence.

Active compounds

1,8-cineole, camphor, α- and β-thujone, sesquiterpene lactones, coumarins, flavonoids

CautionAvoid in pregnancy, as it was traditionally used to provoke menstruation and abortion. Thujone toxicity is possible at high doses. Pollen and food allergy (the 'mugwort–celery–spice syndrome'). Asteraceae allergy.

Marginalia

The Old English Nine Herbs Charm in the 10th-century Lacnunga manuscript names Mucgwyrt first, calling it 'the oldest of plants'. Pliny wrote that a traveller carrying artemisia would not feel weary.

Curiosity

On St John's Eve, medieval Europeans wore mugwort garlands ('St John's girdle') and threw them into the midsummer bonfire to burn away bad luck.
